摘要:
Disclosed is method of making metal nanoparticles comprising, a) adding in no particular order, an aqueous solution of a stabilizing agent solution, an anionic donating solution and a soluble metal salt solution, and b) adding a reducing solution. Also disclosed are metal nanoparticles made by the method.
摘要:
There is provided a system for delivering an oxygen rich lotion. The system uses a single reservoir (4) dispensing bottle (2) that contains a peroxide-rich liquid. The bottle (2) has an outlet (8) within which is a peroxide decomposition catalyst (6) immobilized on a substrate (18), so that the peroxide-rich liquid and immobilized catalyst (6) come in contact with each other just as the liquid is leaving the outlet (8) of the bottle (2).
摘要:
A feeding tube assembly having an improved feeding tube body composed of a tube wall having an external tube surface and an internal tube surface, a proximal end, a distal end separated from the proximal end by a length, and a distal tip region. The internal tube surface defines a feeding passageway extending the proximal end to the distal tip region. The tube body has a first cross- sectional profile from the proximal end to the distal end and at least a second cross-sectional profile from the distal end to the distal tip region. In the first cross- sectional profile, the external tube surface defines an external circumference and the internal tube surface defines a generally non-circular internal perimeter dividing the tube wall into one thin-walled portions and thick-walled portions. In the second cross-section profile, the external tube surface defines an external circumference and the internal tube surface defines an internal circumference.
